Introduction EN

A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set “On” and “Off” periods to suit your own lifestyle. A room thermostat works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached. So a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs and preferences. Setting a programmable room thermostat to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the design and size of the floor heating system.

The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18°C, and then turn it up by 1°C each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money.

You are able to temporarily adjust the heating program by overriding or using the temperature hold feature. Programmable room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may also prevent the thermostat from working properly.

Similarly reducing the temperature setting does not affect how quickly the room cools down. Setting a programmable room thermostat to a lower temperature will result in the room being controlled at a lower temperature, and saves energy.

Installation

4.1 Installation Procedure Do Mount the thermostat at eye level.

3. Connect the thermostat. For more information, see section “7.3 Wiring Diagram” on page 18.

Don’t Do not install near to a direct heat source as this will affect functionality. Do not push hard on the LCD screen as this may cause irreparable damage. This thermostat is designed to be flush mounted and requires a back box of 35mm (minimum depth) to be sunk into the wall prior to installation.

To install the thermostat, follow these steps: 1. Separate the front half of the thermostat from the back plate by placing a small flat head terminal driver into the slots on the bottom face of the thermostat.

4. Screw the thermostat back plate into the back box.

5. Clip the front of the thermostat back onto the thermostat back plate.

NO 2. Place the thermostat front somewhere safe.

Feature 01 – Temperature Format: This function allows you to select between °C and °F.

Feature 03 – Frost Protection: You can set whether the thermostat will maintain the frost temperature when the thermostat display is turned off. As a default, this is enabled. Frost Protection Temperature is changed by using the buttons, while in Frost Protection mode and on the main screen. This is the temperature maintained when the thermostat is in frost protection mode. The range is 07 - 17°C. The default is 12°C and is suitable for most applications.

Feature 04 – Output Delay: To prevent rapid switching, an output delay can be entered. This can be set from 00 - 15 minutes. The default is 00 which means there is no delay. Feature 05 – Temperature Up/Down Limit: This function allows you to limit the use of the Up and Down keys. This limit is also applicable when the thermostat is locked and so allows you to give others limited control over the heating system.

Feature 06 – Sensor Selection: On this thermostat, you can select which sensor should be used. You can select between air temperature only, floor temperature, or both. When you enable both sensors, the floor sensor is used as a floor limiting sensor and is designed to prevent the floor from overheating. Note: Built in air sensor only MUST NOT be used to control electric underfloor heating. Floor sensor only or built in air & floor sensor together must be used.

01 = Programmable (01 default)

(27°C is the default).

00 = Manual

Feature 02 – Switching Differential: This function allows you to increase the switching differential of the thermostat. The default is 1°C which means that with a set temperature of 20°C, the thermostat will switch the heating on at 19°C and off at 20°C. With a 2°C differential, the heating will switch on at 18°C and off at 20°C.

Feature 07 – Floor Temperature Limit: When the Floor Sensor has been enabled in feature 08, you can set a floor limiting temperature between 20-45°C. This protects the floor from overheating.

Feature 08 – Optimum Start: Optimum start will delay the start up of the heating system to the latest possible moment to avoid unnecessary heating and ensure the building is warm at the programmed time. The thermostat uses the rate of change information to calculate how long the heating needs to raise the building temperature 1°C (with a rate of change of 20, the thermostat has calculated the heating needs 20 minutes to raise the building temperature 1°C) and starts the heating accordingly. On this thermostat, optimum start works on the Wake and Return comfort levels.

Feature 09 – Rate of Change: Number of minutes to raise the temperature by 1°C. Feature 10 – Programming Mode: The following programming modes are available:

• 5/2 Day Programming – 4 levels for the weekdays and 4 different levels forthe weekend. • 7 Day Programming – 4 levels for each day. • 24h Programming – 4 comfort levels for 24 hours. Feature 11 – Thermostat Mode: The following thermostat modes are available: • Manual – Basic up/down override temperature control. • Programmable – Schedule 4 levels of comfort.
